Hello list, I'm building a new system with 8 disks, in two RAID5 arrays of 4 disks each, and a RAID1 array across them. (Then LVM2 on top of the RAID1 array.) I approached it this way for two reasons: 1/ It feels "cleanest"; in the sense that it's not a special case, it's just RAID1 with two devices, which happen to be RAID5. 2/ I have a particular usage in mind: I need to be able to split the mirror and remove half; return it later and resync. Therefore, I want to know which disks comprise which halves. However, I'm rethinking toward RAID10. However, I can't find much documentation about layout, etc. I believe this was recently discussed on the list. Can someone with RAID10 experience enlighten me? Can it be cleaned split, half moved to another host, or rejoined with the first half, etc. How about performance? (Not a huge issue, but it is better than nested arrays as I first considered?) Aside, I'd like it to be bootable. I was told grub only supports booting from 0.90 superblocks, but that 0.90 has a 2TB limitation? Meaning, I need /boot with 0.90 and another partition (LVM) with a 1.0 superblocks?
